When a woman is flirting with you here are some things she will do:

She will “flip her hair.” Her palm will be open during this flip. Her palm will be facing you. If she shows you the back of her hand, she is unconsciously telling you she’s taken and is not available.

Also, when a sexy woman is sending you signals she is available, she will look at you in the eye, then drop her eyes down. She may drop her eyes to your chin or drop them all the way to the floor. The more she drops her eyes the more she is into you.

Watch for a woman who is crossing and uncrossing her legs. Actually if she's
bouncing her foot in your direction, it is a good sign.

Next watch for her gently "violating" your personal space. She'll put her hand in there or touch you briefly as she's laughing.

Watch for her voice to lower half an octave.See if she tucks in her blouse.
One of the more overt ones is, touching you just for a moment. Laughing.

For women, humor is part of the game that men just ignore. Not if she's
laughing at you, but if she's laughing with you. Laughter to her is a bonding
experience.

If you can make women laugh, you're much closer to getting what you want.
